Exporting jupyter notebook to pdf with offline plotly graph; missing graphs

Question

I am trying to create pdf export of my lesson plans and I use plotly offline for the graphs. In a MWE below, the plot will display in the Jupyter Notebook but will not show up when I export to pdf. I export using File-->Download as-->PDF via Latex (.pdf).

I'd like to make a pdf instead of using html. I understand it might take an extra step to convert an html export to pdf, but I was just wondering if there was a more direct route (a code modification?) that would allow me to export directly through File-->Download as-->PDF via Latex (.pdf)

from plotly.offline import download_plotlyjs, init_notebook_mode, iplot
init_notebook_mode(connected=True)
import plotly.graph_objs as go

data = [go.Scatter(
    x=[1, 2, 3],
    y=[3, 2, 1])
]
iplot(data)

Answer 1

You need to specify the appropriate Default Renderer (or Renderers, if you want to visualize it in the Notebook and also when exporting to PDF using the File-->Download as-->PDF via Latex (.pdf) option you mentioned).

I have been struggling with this myself for some hours too, but the setup that ended up working for me is the following:

import plotly.io as pio
pio.renderers.default = "notebook+pdf"  # Renderer for Notebook and HTML exports + Renderer for PDF exports
# init_notebook_mode(connected=True)  # Do not include this line because it may not work

Note that you can concatenate as many Renderers as you want using the + symbol, and Plotly will magically know when to use each of them.
